ROWID
The ROWID returns the rowid (binary address) of a row in the database table. You can use the variables of the type UROWID to store rowids in a readable format. In the illustration below, you declare a variable named row_id for that reason:
DECLARE
row_id UROWID;
Whenever you select or fetch a rowid into a UROWID variable, you can use the function ROWIDTOCHAR that converts the binary value to an 18-byte character string. Then, you may compare the UROWID variable to the ROWID pseudocolumn in the WHERE clause of an UPDATE or DELETE statement to recognize the latest row fetched from a cursor.
